TM11-5830-263-20&P
WARNING
HIGH VOLTAGE
IS USED IN THE OPERATION OF THIS EQUIPMENT.
DEATH ON CONTACT
MAY RESULT IF PERSONNEL FAIL TO OBSERVE SAFETY
PRECAUTIONS.
NEVER WORK ON ELECTRONIC EQUIPMENT UNLESS THERE IS ANOTHER
PERSON NEARBY WHO IS FAMILIAR WITH THE OPERATION AND HAZARDS OF
THE EQUIPMENT AND WHO IS COMPETENT IN ADMINISTERING FIRST AID. WHEN
THE TECHNICIAN IS AIDED BY OPERATORS, THEY MUST BE WARNED ABOUT
DANGEROUS AREAS.
BE CAREFUL NOT TO CONTACT HIGH-VOLTAGE CONNECTIONS OF THE AC
INPUT CONNECTIONS WHEN INSTALLING OR OPERATING THIS EQUIPMENT.
WHENEVER THE NATURE OF THE OPERATION PERMITS, KEEP ONE HAND AWAY
FROM THE EQUIPMENT TO REDUCE THE HAZARD OF CURRENT FLOWING
THROUGH VITAL ORGANS OF THE BODY.
WARNING
DO NOT BE MISLED BY THE TERM "LOW VOLTAGE". POTENTIALS AS LOW
AS 30 VOLTS MAY CAUSE DEATH UNDER CERTAIN CONDITIONS.
FOR ARTIFICIAL RESPIRATION, REFER TO FM 21-11.
WARNING
WHEN LISTENING TO THE VIS RADIO HEADSET WITH THE OPERATOR VOLUME
CONTROLS SETTING IN THE RED ZONE CLICK STOP AT A FULL ON VOLUME
SETTING, EXTREME CAUTION MUST BE EXERCISED TO PREVENT NOISEINDUCED HEARING LOSS. EXPOSURES TO RADIO SIGNALS IN THE FULL ON
POSITION BEYOND 45 SECONDS MAY CAUSE HEARING LOSS. ANY PROLONGED
EXPOSURE IN THE FULL ON VOLUME CONTROL SETTING REQUIRES THE USE
OF A SINGLE HEARING PROTECTIVE DEVICE IN EACH EAR.
WARNING
WHEN INSTALLING REPLACEMENT BATTERY IN THE CVC HELMET BATTERY
COMPARTMENT, DO NOT PLACE ALKALINE AA BATTERY IN THE RECHARGEABLE
SLOT. PLACE THE ALKALINE AA BATTERY IN THE ALKALINE SLOT ONLY.
ALKALINE BATTERIES MAY EXPLODE OR LEAK IF RECHARGED OR CONNECTED
IMPROPERLY.
b
TM-11-5830-263-20&P
WARNING
ALKALINE BATTERIES CONTAIN CAUSTIC KOH ELECTROLYTE, WHICH MAY LEAK
IF THE BATTERY IS ABUSED. KOH IS A STRONG ALKALI SIMILAR TO CAUSTIC
SODA (SODIUM HYDROXIDE). SERIOUS CHEMICAL BURNS CAN RESULT IF
ELECTROLYTE COMES INTO CONTACT WITH THE SKIN OR EYES. IF THE
BATTERY ELECTROLYTE GETS INTO YOUR EYES, IT CAN CAUSE SEVERE
DAMAGE AND/OR BLINDNESS.
DO NOT TRY TO NEUTRALIZE CAUSTIC ELECTROLYTE WITH VINEGAR OR ANY
OTHER ACIDIC SOLUTIONS. NEUTRALIZATION WILL DO MORE HARM THAN
GOOD, AS IT WILL TRAP CAUSTIC UNDER THE SKIN, PREVENTING IT FROM
COMING OUT. FLUSH WITH COPIOUS AMOUNTS OF COOL WATER.
WARNING
DISCONNECTING OR BYPASSING THE VEHICULAR INTERCOMMUNICATION
SYSTEM (VIS) ALARM CABLE CONNECTED TO THE DRIVER’S FULL FUNCTION
CREW STATION (FFCS) BY THE VEHICLE CREWMAN IS PROHIBITED. SUCH
ACTION MAY RESULT IN INJURY OR DEATH. EQUIPMENT DAMAGE MAY ALSO
RESULT. THIS CABLE ENABLES THE VEHICLE HAZARD WARNING TONES TO BE
INSERTED DIRECTLY INTO THE INTERCOM SYSTEM, SO THAT THESE WARNING
TONES CAN BE INSTANTLY HEARD BY ALL OF THE VEHICLE CREWMEMBERS.
ONLY THE UNIT MAINTAINER IS AUTHORIZED TO REMOVE AND REPLACE THE
ALARM CABLE. REFER TO THE APPROPRIATE VIS TECHNICAL PUBLICATIONS
FOR OPERATOR, INSTALLATION, AND MAINTENANCE INSTRUCTIONS.

GENERAL INFORMATION
SCOPE
This technical manual contains instructions for troubleshooting and corrective maintenance for the
AN/VIC-3, Vehicular Intercommunication Set, commonly known as the Vehicular Intercommunication Set
(VIS), as well as a "Repair Parts and Special Tools List' Appendix listing the parts required to maintain the
equipment.
a. Type of manual: Unit Maintenance Manual (Including Repair Parts and Special Tools List).
b. Model Number and Equipment Name: The official nomenclature is the AN/VIC-3(V)
Intercommunication Set, Vehicular, with its common name being the Vehicular
Intercommunication Set (VIS). There are many current and future variations of this system
designed for specific vehicles and/or platforms, each with its own unique technical bulletin for
installation. Refer to Table 1 -1 (at the end of this section) for the VIS version, vehicle /platform
it's installed in, and the corresponding installation technical bulletin. These vehicle/platform
specific variations have meaning only to the installation team as the system loses its identity
when installed. Any vehicle/platform that has this system installed is referred to as having the VIS
or "VIC-3"(AN/VIC-3(V)).
c.
Purpose of Equipment: The AN/VIC-3(V) is an intercommunication and radio-control system
designed for ground mobile combat vehicles. Digital audio enhances speech quality and
intelligibility. Headsets that incorporate active noise reduction (ANR) circuitry increase the
effectiveness of vehicle communications. They offer increased hearing protection in the noisy
environment of combat vehicles.
d. Equipment Components. The AN/VIC-3(V) or VIS is a variety of installation kits designed for
specific vehicles and/or platforms. The VIS is designed to replace the AN/VIC-1, in some cases
utilizing the existing mounting hardware and brackets used by the AN/VIC-1. Kits consist of the
following components, the type and quantity of which vary depending upon the specific vehicle
and/or platform: Line Replaceable Units (LRUs (Boxes)) (Figure 1-1); cables (highway, power,
alarm, etc.); headsets; brackets; and mounting hardware for securing LRUs and brackets. The
RPSTL (Appendix C) of this manual only identifies the mounting hardware that is removed and
replaced as part of the maintenance procedures associated with the VIS. If the bracket, and/or
mounting hardware used to secure it, need replacing, refer to the appropriate installation
technical bulletin, Table 1-1, to identify the correct Part Number (PN) / National Stock Number
(NSN).

CORROSION PREVENTION AND CONTROL
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any
corrosion problems with this item be reported so that the problems can be corrected and improvements
can be made to prevent the problem in the future.
While corrosion is typically associated with rusting of metals, it can also include deterioration of other
materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these
materials may be a corrosion problem.
If a corrosion problem is identified, it can be reported using SF 368, Product Quality Deficiency Report.
Use of key words such as "corrosion", "rust", "deterioration", or "cracking" will ensure that the information
is identified as a CPC problem.
The form should be submitted to the address specified in DA PAM 738-750, Functional User's Manual for
the Maintenance Management System (TAMMS).

DIFFERENCES BETWEEN MODELS
The AN/VIC-3(V) is an installation kit with multiple versions designed for specific vehicles and/or
platforms. Table 1-1. "MODULE NUMBER AND INSTALLED VEHICLE /PLATFORM NAMES" in Section
1 of this chapter identifies the specific vehicle/platform that each version of the kit is installed in.
All kits contain one Master Control Station (MCS) and a minimum of two Full Function Crew Stations
(FFCS). Some kit versions also contain Monitor Only Stations (MOS). The MCS has connections for 2
radios. For those vehicles/platforms that utilize more than two radios, a Radio Interface Terminal (RIT) is
added to the kit. Each RIT allows two additional radios to be hooked up. The VIS can operate a maximum
of six radios (1 MCS plus 2 RITs) at any one time.
Additionally, the installation kits contain various types (power, highway, alarm, etc.) and quantities of
cables. Also supplied with the kits are various type of brackets and plates, along with the mounting
hardware needed to secure them to the vehicle and/or platform. The Mounting hardware to secure the
LRUs (Line Replaceable Units), (MCS, FFCS, etc.) to these brackets and plates is also included. In some
vehicle/platform installations, existing brackets, plates and mounting hardware is utilized in conjunction
with the hardware that is provided in the installation kits for the VIS.

SECTION III PRINCIPLES OF OPERATION
1.12.
GENERAL OVERVIEW OF SYSTEM OPERATION
Refer to TM 11-5830-263-10, Chapter 1, Section 1, paragraph 1.10 for general overview of system
operation.
1.13.
POWER DISTRIBUTION
Power enters the MCS through the power connector and an Electromagnetic Compatibility (EMC) filter,
which also provides reverse polarity and transient-spike protection. From this point, the power supply
circuitry is split into two individual supplies: (1) the VIS regulated dc power supply, and (2) the ANR
isolated power supply. Both power supplies provide identical power conditioning circuitry. This
conditioning circuit provides overvoltage, undervoltage, and overcurrent protection. In the case of over
(40Vdc) or under (15Vdc) voltages occurring, the circuit shuts off power to the system until the voltage
returns to within the system's operating range. If the circuitry senses excessive amps from its power
supply, the overcurrent electronic circuit breaker for that power supply will trip, removing power. This is
detected by an internal circuit within the MCS and indicated on the MCS's POWER FAULT LED
(SYSTEM or ANR) display as being an overcurrent condition. To reset either circuit breaker, the SYSTEM
switch on the MCS is turned to "off" then back to one of the "on" positions.
The regulated system power supply provides +5Vdc and -5Vdc for the MCS internal circuitry and supplies
power to the other VIS modules via the highway cables.
The ANR power supply provides a +24Vdc regulated voltage that is connected into the system highway to
power the ANR modules in the headsets.
The PTT switch on the headset, set in the momentary position for transmission over a selected radio, has
a maximum input voltage and current of 35Vdc and 50 mA.
1.14.
DATA TRANSMISSION
The system component parts function to allow integration of vehicle crew internal communications and
radio communication in a ring bus configuration. The system communication scheme, Time Division
Multiple Access (TDMA), is synchronized by the MCS. VIS appends 1 of 32 destination addresses to
each byte of digital data. Of these 32 addresses, 16 have been allocated for up to 8 radios (1 for transmit
and 1 for receive for each radio), 4 have been allocated for intercom, 1 for control, with 11 addresses
remaining as spares for future system growth. (VIS currently uses a maximum of 6 radios.) The MCS
regulates the timing of the digital packets of information, which may be initiated from any other station
except the MOS. The MOS can receive audio information but cannot transmit. The distribution of audio
(intercom) to the MOSs is achieved in an analog format; however, the audio power amplification is
individually controlled at each MOS to prevent volume fluctuations when crewmembers connect or
disconnect their headsets. This approach also isolates the headsets from the audio source, increasing the
survivability of the system if a particular headset becomes damaged or short-circuited. The FFCS allows
an operator full access to all radio and intercom communications and provides the operator with
microphone keying options. Each RIT interfaces with two radios. When multiple RITs are connected to
the ring bus, up to six radios can be interfaced. This includes the two radios interfaced to the MCS. The
MCS and RIT convert analog radio signals from analog to digital and place the packets of information on
the bus, which allows the commander and crew to select the digitized audio information in various
combinations. They also convert FFCS audio from digital to analog for transmission over the radios. The
FFCS then selects which packets of radio information it requires and converts the digitized audio to
analog. The FFCS also communicates over the intercom to maintain internal communication between
crewmembers and communicates to the MCS and RIT for external radio traffic.
1-7
TM11-5830-263-20&P
Further, audio levels can be controlled to accent internal communication in emergency conditions. The
system interfaces with a loudspeaker and various types of headsets (CVC, CAPS, ACAPS, and CCH);
the loudspeaker connects to the MCS or to any FFCS/MOS and allows one-way communication to crew
or troops either being transported or working in close proximity to the vehicle.
The system incorporates an Auto Reconnect Circuit (ARC) that continually monitors the system bus. If a
break occurs in the ring bus, the ARC automatically restores system connectivity and informs the operator
of the malfunction.
1.15.
VIS CABLING
VIS is interconnected using a single type of cable called a highway cable. Data, power, and analog
signals are carried by a seven-conductor cable, which incorporates internal and external shields as
shown in figure 1-2. The external shielding prevents cross talk from external sources; the internal
shielding prevents cross talk internal to the cable. This cable carries the VIS data bus on the inner
shielded twisted-pair of conductors. Two conductors carry conditioned system power for distribution to all
units, two conductors carry the conditioned Active Noise Reduction (ANR) power, and the seventh
conductor carries the analog audio signal for the MOSs. The two shields are combined with the zero volts
ground on the vehicle body. The power supply conductors and intercom audio are connected in a ring.

Figure 1-2. Highway Cable Construction
a. Partial Cable Failure – The data bus conductors are not connected in a complete ring but as a
bus which originates and terminates inside the MCS on the Automatic Reconnect Circuit (ARC).
The ARC monitors data bus activity at the terminating end of the bus. In normal operation there
will always be activity on the bus. If the ARC detects no bus activity (i.e., a break has occurred
somewhere on the data bus) it instantly activates the re-route circuit, connecting the originating
and terminating ends of the bus, thereby automatically reconnecting those units located
"downstream" of the cable break. The ARC is so quick in reconnecting the bus that its operation
normally goes unnoticed by the crew; therefore to alert the crew that a cable break has occurred,
the CPM reports a "ring unconnected (ru)” fault on the MCS display.
b. Total Cable Failure – If any single VIS cable is totally severed, the system will continue to
operate without degradation in performance. The system reconfigures itself automatically (i.e.,
power is still available to each unit; the ARC detects the break and reconnects any unconnected
units; a "ring unconnected (ru)” warning is displayed on the MCS by the CPM).
1-8
TM-11-5830-263-20&P
c. Partial Cable Severing –
•
If any cable is partially severed, the system will continue to operate without any performance
degradation.
•
If either or both conditioned power conductors are severed, power is still available at each
unit. With both data-bus conductors still intact, the ARC will not close.
•
If either or both ground conductors are severed, ground returns are still available because of
the ring architecture. Again, with both data conductors still intact, the ARC will not be
triggered.
•
If either or both data bus conductors are severed, the ARC will trigger, reconnecting any
unconnected units instantly.
•
If the ground shields are totally severed, the ground is carried around the ring in both
directions by the cable and also through the vehicle body to each FFCS, MOS, and RIT. The
loss of shielding is not significant and will not affect the operation of the system.
d. Partial Cable Severing with Shorted Conductors –
•
If a cable is partially severed and the conductors are shorted together, the system cannot
continue to operate normally. None of the units will be damaged internally, no matter which
leads are shorted.
•
Either data bus conductor may be shorted to either of the power conductors, either of the
grounds, or the zero volts ground shield without affecting the VIS operation. The transformer
coupling of the data bus to each unit prevents damage.
•
If the data bus conductors are shorted together, or both to ground, or both to the same
conditioned power conductors, the data bus cannot function. All communications will cease
and the CPM software will cause the MCS to display in sequence that all units in the system
have become unconnected (e.g., 1 u, 2u, 3u, 4u, Au, Bu.... ru), showing that the whole data
bus has been stopped. As soon as the damaged cable is disconnected, all communications
are restored.
•
If the +28Vdc conditioned system power conductor is shorted to the zero volts ground, the
MCS system power conditioning circuit overcurrent limit will trip at approximately two amps.
The system is then effectively isolated from power and only a single LED on the MCS display
will be illuminated. This would indicate that the overcurrent limit circuit has tripped. In this way
the system isolates itself from further damage. The ANR power supply will remain intact,
allowing ANR protection to remain operational. For immediate corrective action, the faulty
cable section will be disconnected. Following disconnect, replacement or repair of the
damaged cable, the trip circuit may be reset by switching the MCS SYSTEM switch to "off"
and then back to one of the "on" positions, restoring full system operation.
•
If the +24Vdc conditioned ANR power conductor is shorted to the zero volts ground, the MCS
ANR power-conditioning circuitry will operate its overcurrent limit trip circuit. This circuit is set
to trip at approximately two amps. ANR equipment will then cease to operate and the MCS
CPM will indicate that the overcurrent limiter has tripped while the VIS system will continue to
operate normally. Following replacement or repair of the damaged cable, the trip is reset by
switching the MCS SYSTEM switch to "off” and then back to one of the "on" positions.

1.16.
BATTLE DAMAGE DESCRIPTION
Battle damage control in the VIS is made possible by redundant paths in the highway - cable ring
architecture. The system continues to function if there is a single break in any of the cables or the paths
within the crew boxes that carry power, data signals, or analog audio. Special circuitry within the MCS
and each of the FFCS and RIT boxes comes into play if the data signal path is broken. If the MCS does
not sense receipt of the digital data stream at its bottom STATION connector, it recognizes that there is a
break in the path and initiates transmission from the bottom connector to communicate with the
disconnected portion of the ring. (This involves operation of an internal relay that removes a terminating
resistor from the data path and inserts the same signal transmitted at the top station connector.)
The break in the data path is also sensed and accommodated by the digital boxes on either side of the
break. (A dc bias on the two data lines forming the path segment interconnecting adjacent boxes
activates a zener diode circuit that applies terminating resistors to prevent signal reflections from both
sides of the break in the data path.) The system continues to provide communication to all crew stations,
and "ru" is displayed by the MCS to indicate that maintenance is required. (The dc bias voltage of
approximately 20 volts provides a convenient method to verify continuity to connectors within FFCSs and
RlTs during troubleshooting.)

CAUTION
BE SURE TO REMOVE POWER FROM THE MCS BEFORE DISCONNECTING OR
REMOVING AND REPLACING COMPONENTS AND/OR CABLES.
2.1.
GENERAL
If a troubleshooting procedure identifies a piece of equipment as defective refer to Chapter 3 of this
manual for all Removal and Replacement Procedures. Section III of the Maintenance Allocation Chart
(MAC) in Appendix B contains a list of all tools and test equipment required to troubleshoot the Vehicular
Intercommunication Set (VIS). Appendix C contains the Repair Parts and Special Tools List (RPSTL)
identifying the piece parts for repair.
2.2.
SCOPE OF UNIT TROUBLESHOOTING
Unit maintenance involves confirmation of operational problems reported by VIS users, diagnosis of
confirmed problems, and problem correction usually by replacement of units found to be faulty. Problems
may be identified by physical inspection of damaged equipment, by specific failure indications such as an
illuminated fault light or an inability to communicate, or by an alphanumeric error indication on the MCS
display. To adequately troubleshoot VIS, the unit maintainer is required to have one spare MCS and one
spare RIT (if vehicle has only one RIT normally).
2.3.
EQUIPMENT INSPECTIONS/CHECKS/GUIDELINES
Prior to beginning any troubleshooting procedures always review the report of the user problems and
verify if possible by observation. Sections IV, V, and VI of this chapter cover, respectively:
•
•
•
Troubleshooting system problems that "do not' show up as errors on the alphanumeric display.
Troubleshooting system problems that "do" show up as errors on the alphanumeric display.
Troubleshooting cable assemblies.
Before initiating any of the troubleshooting procedures in Sections IV, V, and VI there are some checks
that can be accomplished. These checks, as well as the troubleshooting procedures in later sections,
involve utilizing the VIS Operator's Manual, TM 11-5830-263-10. The checks are as follows:
2-1
TM11-5830-263-20&P
a. Loudspeaker and/or Loudspeaker Cable Problems.
1. Turn MCS off and disconnect Loudspeaker cable at MCS if connected.
2. Turn MCS on. If problem has disappeared, turn MCS off and reconnect Loudspeaker cable.
3. Turn MCS on. If problem reappears, turn MCS off and substitute with known good
Loudspeaker and cable.
4. Turn MCS on If problem disappears, Loudspeaker and/or cable may be faulty. Refer to the
troubleshooting procedures in Sections IV and VI.
5. If problems reappear, MCS may be faulty. Refer to the troubleshooting procedures in Section
IV.
b. Do a system configuration (as explained in the Operator’s manual). Verify what the MCS
identifies as connected in the ring and that it corresponds to the vehicle placard located next to
the MCS in the vehicle, or as shown on the Equipment Location Diagram for the specific vehicle
in Section II of this chapter. If there is not a match with what the MCS identifies and what is on the
vehicle placard then the following may have occurred:
1. Cables may be disconnected, in which case they need to be physically inspected and
reconnected.
2. The FFCS or RIT have not been correctly set, in which case they need resetting. The
procedures for setting the crewstation/radio switch for the FFCS/RIT can be found in Section
III of this chapter.
3. If cables are connected, and the FFCS and RIT are properly set and problems still exist in
terms of the system configuration mode then refer to the troubleshooting procedures in
Section IV.
c.
If the system is properly configured, place the SYSTEM switch on the program being utilized
(PROG 1, 2, or 3,), and the PROGRAM switch on VIEW. Observe the levels of radio access
programmed into the MCS. If discrepancies are noted reprogram the MCS using the Operator's
manual. If discrepancies still exist, or the MCS will not program, refer to the troubleshooting
procedures in Section IV.
SECTION II
2.4.
EQUIPMENT LOCATION AND SYSTEM CONFIGURATION DIAGRAMS
GENERAL
As stated in the previous section problems with the VIS can occur in various forms. System problems may
occur without showing up as error messages on the alphanumeric display, or system problems may occur
that do show up as error messages on the alphanumeric display. Corrective action for the VIS involves
principally the replacement of a single unit (box or cable), or, in the case of a headset, a component part.
The procedures apply whether trouble is in radio or intercom communications. Damage to more than one
VIS unit is beyond the scope of these procedures. In the event of suspected damage to multiple units, the
general approach is to disconnect all units from the system, then add the units in sequence to the system
one at a time for evaluation. Following this general approach isolates individual boxes, so that in effect,
possible multiple faults are reduced to single faults that are troubleshot one at a time. Whenever
troubleshooting the VIS extensive use should be made of the Operator's Manual, TM 11-5830-263-10.
Procedures for correctly setting the FFCS and RIT can be found in Section III of this chapter.

TROUBLESHOOTING USING THE EQUIPMENT LOCATION AND CONFIGURATION
DIAGRAMS
a. From the System Configuration Diagram for your vehicle, determine whether units are connected
by highway cables in a ring configuration (as most vehicles are) or are connected in a two-branch
configuration.
b. If your vehicle is connected in a ring configuration, refer to Table 2-4 for a listing of MCS
alphanumeric error messages with their corrective measures. If your vehicle is connected in a
two-branch configuration refer to Table 2-5 for a listing of MCS alphanumeric error messages with
their corrective measures
c. After performing each corrective measure, power the MCS off then back on and check for normal
operating indications on the equipment. Use a Multimeter, the specific type and model of which
can be found in Section III of the Maintenance Allocation Chart, to measure vehicle battery
voltage and to check cable continuity. Cable troubleshooting is covered in Section VI.

FFCS AND RIT CREW STATION/RADIO SWITCH SETTING PROCEDURES
FFCS CREW STATION ADDRESS SWITCH SETTING PROCEDURES (FIG. 2-37.)
Perform the following procedure to change the FFCS Crew Station Address switch setting located on the
bottom of the FFCS.
a. Rotate switch cover screw counterclockwise and remove.
b. Using a jeweler’s screwdriver, rotate the adjustment screw counterclockwise, until stop is
reached. This is the setting for Crew Station #1.
c.
Each click of the switch in a clockwise direction changes the address by one position. For
example, with the switch in the full ccw position (Crew Station #1), turning the switch two clicks in
a clockwise direction will set the FFCS to Crew Station #3.
d. The address switch has 8 positions. Crew Station settings are numbered 1 through 6. Position 7
on the switch is the same as position 6. Position 8 on the switch is normally used for testing,
however, if the MCS is not functioning correctly, e.g., loss of timing signal (sync pulse), but is
supplying power to the rest of the system, setting the switch to position 8 will result in the FFCS
putting out a timing signal like the MCS.
e. When the correct Crew Station address has been set replace switch cover screw and hand
tighten.

RIT RADIO SELECTION SWITCH SETTING PROCEDURES (FIG. 2-38.)
Perform the following procedures to set the Radio Selection Switch on RIT.
NOTE
The following procedures can only be performed when the RIT is dismounted.
a. Remove the switch protective cover from rear plate of RIT using a spanner wrench, and rotating
counterclockwise.
b. Using a jeweler's screwdriver turn switch counterclockwise to stop, this sets the RIT to Radio's
C/D.
c. Turning the switch clockwise one position sets the RIT to center position. This position is used for
testing, however, if the MCS is not functioning correctly, e.g., loss of timing signal (sync pulse),
but is supplying power to the rest of the system, setting the switch to this position will result in the
RIT putting out a timing signal like the MCS.
d. Turning the switch clockwise one more position sets the RIT to Radio E/F.
e. When the correct Radio setting position for the RIT has been made, replace switch protective
cover using spanner wrench and tighten.

TROUBLESHOOTING WITH NO ERROR MESSAGE DISPLAY
a. General
The procedures in step b below troubleshoot faulty equipment in VIS not indicated on the MCS
alphanumeric display. They apply whether trouble is in radio or intercom communication. If an
error message is displayed, refer to Section V. See Table 2-2 for the troubleshooting flowchart(s)
to correct the fault.
b. Troubleshooting the system
Perform the following steps in sequence, to ensure accurate troubleshooting of the equipment:
System Troubleshooting Chart, Table 2-2, lists symptoms of faults in priority order. Start with the
lowest test number on Table 2-2 that resembles the current fault. If a test number is skipped, it is
assumed that symptom has not occurred.

GENERAL INFORMATION
SCOPE
This chapter covers removal and replacement procedures for three major groups of AN/VIC-3(V) or VIS
(Vehicular Intercommunication Set) equipment: the Line Replaceable Units (LRU) (MCS, FFCS, RIT,
MOS, LOUDSPEAKER), the Headset Components and the VIS Cabling (Highway, Power, Alarm, etc.).
Additionally, Removal and Replacement Procedures for the Knobs on the LRU’s are also covered.
SECTION II
LRU REMOVAL AND REPLACEMENT PROCEDURES
CAUTION
REMOVE POWER FROM THE MCS BEFORE REMOVING OR REPLACING
COMPONENTS/CABLES. FAILURE TO DO SO MAY RESULT IN DAMAGE TO
COMPONENTS.
NOTE
Verify the crewstation(s) setting (1,2,3,4,5,6) for the FFCS and/or radio settings for the
RIT(C/E, D/F) being removed so that the replacement FFCS/RIT can be correctly set. For
instructions on setting the FFCS/RIT refer to the appropriate paragraph in Chapter 2.
The LRU’s (MCS, FFCS, RIT, MOS) are mounted on studs or plates utilizing varying sequences of
grounding straps and/or washers (lock and flat), and secured with either nuts or bolts. Paragraph 3.7 at
the end of this section lists tables and figures showing the mounting sequences associated with the
various LRU’s. Refer to paragraph(s) 3.2 through 3.6 for removal and replacement procedures and
instructions for the appropriate LRU. It should be noted that although some of the mounting sequences
for LRUs for various vehicles look identical the actual parts might differ. Refer to the Repair Parts and
Special Tools List (RPSTL) in Appendix C for proper identification of the correct part.

PROCEDURES
3.8.
COMBAT VEHICLE CREWMAN (CVC) HEADSET COMPONENTS REMOVAL AND
REPLACEMENT PROCEDURES
There are two designs of CVC headset (See Figure 3-10). The newer design, commonly
referred to as “Product Improved” CVC (PICVC), has a one-piece microphone, boom,
and cable assembly which is interchangeable with the earlier design CVC. Additionally,
the PICVC has talk thru circuit (TTC) capability powered by either a rechargeable or AA
alkaline battery located in a compartment situated on the left earcup. The new PICVC
utilizes two liners (large, medium) instead of the three liners (large, medium, small) used
the previous model CVC. All the liners are interchangeable with regards to the earcups
and cable assembly fitting into them. The pads installed in the PICVC liner have been
improved and can be removed and replaced. These pads, which come in large and
medium kit sizes, are interchangeable with the pads in the earlier design CVC liner. The
set of large pads is installed in both large liners. The set of medium pads is installed in
both medium liners as well as the CVC small liner.

MAINTENANCE ALLOCATION CHART (MAC)
FOR INTERCOMMUNICATION SET, VEHICULAR, AN/VIC-3(V)
SECTION I
INTRODUCTION
B-1 GENERAL
a. This section provides a general explanation of all maintenance and repair functions authorized at
various maintenance categories.
b. The Maintenance Allocation Chart (MAC) in Section II designates overall authority and
responsibility for the performance of maintenance functions to the end item or component. The
application of the maintenance functions to the end item or component will be consistent with the
capacities and capabilities of the designated maintenance categories.
c. Section III lists the tools and test equipment (both special tools and common tool sets) required
for each maintenance function as referenced from Section II.
d. Section IV contains supplemental instructions and explanatory notes for a particular maintenance
function.
B-2 MAINTENANCE FUNCTIONS
Maintenance functions will be limited to and defined as followed:
a. Inspect. To determine the serviceability of an item by comparing its physical, mechanical and/or
electrical characteristics with established standards through examination (e.g. by sight, sound, or
feel).
b. Test. To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical
characteristics of an item and comparing those characteristics with prescribed standards.
c. Service. Operations required periodically to keep an item in proper operating condition, i.e., to
clean (includes decontaminate, when required), to preserve, to drain, or to replenish fuel, lubricants,
chemical fluids, or gases.
d. Adjust. To maintain or regulate, within prescribed limits, by bringing into proper or exact
position, or by setting the operating characteristics to specified parameters.
e. Align. To adjust specified variable elements of an item to bring about optimum or desired
performance.
f. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments or
test measuring and diagnostic equipment used in precision measurement. Consists of comparisons
of two instruments, one of which is a certified standard of known accuracy, to detect and adjust any
discrepancy in the accuracy of the instrument being compared.
B-1
TM 11-5830-263-20&P
B-2 MAINTENANCE FUNCTIONS - Continued
g. Remove/Install. To remove and install the same item when required to perform service or other
maintenance functions. Install may be the act of emplacing, seating, or fixing into position a spare,
repair part, or module (component or assembly) in a manner to allow the proper functioning of an
equipment or system.
h. Replace. To remove an unserviceable item and install a serviceable counterpart in its place.
Replace is authorized by the MAC and is shown as the third position code of the SMR code.

i. Repair. The application of maintenance services , including fault location/troubleshooting ,
3
4
removal/installation, and disassembly/assembly , procedures, and maintenance actions , to identify
troubles and restore serviceability to an item by correcting specific damage, fault, malfunction or
failure in a part, subassembly, module (component or assembly), end item, or system.
j. Overhaul. That maintenance effort (service/action) prescribed to restore an item to a completely
serviceable/operational condition as required by maintenance standards in appropriate technical
publications (i.e., DMWR). Overhaul is normally the highest degree of maintenance performed by
the Army. Overhaul does not normally return an item to like new condition.
k. Rebuild. Consists of those services/actions necessary for the restoration of unserviceable
equipment to like new condition in accordance with original manufacturing standards. Rebuild is the
highest degree of material maintenance applied to Army equipment. The rebuild operation includes
the act of returning to zero those age measurements (hours/miles, etc.) considered in classifying
Army equipments/components.
B-3 EXPLANATION OF COLUMNS IN THE MAC, SECTION II

HOW TO LOCATE REPAIR PARTS
a. When National stock number or part number is not known.
1.
First. Using the table of contents, determine the assembly group or subassembly group to
which the item belongs. This is necessary since figures are prepared for assembly groups and
subassembly groups, and listings are divided into the same groups.
2.
Second. Find the figure covering the assembly group or subassembly group to which the item
belongs.
3.
Third. Identify the item on the figure and note the item number.
4.
Fourth. Refer to the Repair Parts Lists for the figure to find the part number for the item
number noted on the figure.
5.
Fifth. Refer to the Part Number index to find the NSN, if assigned.
b. When National stock number or part number is known.
C-7
1.
First. Using the index of National stock numbers and part numbers, find the pertinent National
stock number or part number. The NSN index is in National item identification number (NIIN)
sequence (para. C-4a1). The part numbers in the part number index are listed in ascending
alphanumeric sequence (para. C-4b). Both indexes cross-reference you to the illustration
figure and item number of the item you are looking for.
2.
Second. After finding the figure and item number, verify that the item is the one you’re looking
for, then locate the item number in the repair parts list for the figure.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly
available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that
sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not
letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share,
republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please
provide a link to liberatedmanuals.com, so that free manuals come up first in
search engines:
